Marginal effects are percentage point increases. Estimates in bold are significant at the 5% level, estimates in italics are significant at the 10% level.
2
Adjusted marginal effects control for major occupation category, work hours, health status, education, demographics and household structure. Referent groups are: professional and related occupations, fair or poor health, Kessler 6 score below 12, non-smoker, education level of high school or less, male, 25–29 years old, non-Latino white ethnicity, married, no children under 12 in household, a household size less than 4, and household income less than $16,601.
